1. Technology Platform & Current Capability The IPAW60R280CEXKSA1 is based on an older CoolMOS™ platform with a rated current of 19.3A (Tc). The IPAW60R280P7SXKSA1 belongs to the CoolMOS™ P7 platform, with a current rating of only 12A (Tc). The P7 version offers approximately 38% lower saturation current capability in the same package. This reflects a fundamental difference in chip size and thermal design philosophy, with the P7 generation prioritizing switching performance over DC load capability. 2. Dynamic Parameters & Switching Performance The P7 device features significantly lower Qg (18 nC) compared to the CE version (43 nC), along with a smaller Ciss. This indicates superior switching speed and lower switching losses for the P7, making it particularly suitable for high-frequency applications (e.g., LLC, PFC). However, note its higher Vgs(th) (4V vs. 3.5V), which may lead to incomplete turn-on under low gate drive voltage conditions. 3. Thermal Design Margin The maximum power dissipation for the CE device is 32W (Tc), compared to 24W (Tc) for the P7. Despite having the same Rdson, the P7's lower thermal dissipation capability may result in a higher junction temperature under identical operating conditions, necessitating a re-evaluation of the heatsink design. 4. Rdson Test Condition Discrepancy Both devices are specified at 280mΩ Rdson, but the test current differs (CE @ 6.5A, P7 @ 3.8A). This reflects a divergence in their conduction characteristic curves. The P7 may exhibit a relatively higher Rdson in the low-current region, potentially affecting light-load efficiency. > Additional Recommendation: Substitution could be cautiously evaluated if the goal is to increase switching frequency or reduce driving losses, provided the peak operating current is ≤10A and sufficient thermal margin exists. Otherwise, priority should be given to selecting a part from the same platform or with a similar current rating.
